I started letting them mingle when my babies were 10 weeks old but they were in separate coops. They all free range so I would let the babies out only when I was there to watch and make sure everything was ok. When they were 12 weeks old I let them free range together. They are 17 weeks old today and they are in the same coop now. The only problem I have right now is Butch my BO has 4 babies that are 5 weeks old and she is VERY protective of her kids so she likes to chase the 17 week olds even when they are not even close to her or the babies! She will sneak up on them and start chasing them! Hopefully when she is done raising her babies she will get back to normal. But I wouldn't wait to long I think its better to start them younger and they also learn from the older flock. which isn't always goodI have a question... how do I know when it's time to take the gate away for the little ones to get away from the big ones? I imagine they would want it there forever but I'm pretty sure I gotta just go for it one of these days.
The little ones are 12 weeks old and the CCL are nearly as tall as the smallest older girls and my EE's aren't far behind. They would still have a few other places to sort of hide if needed. They still sleep in their own coop and that won't change until about mid Sept. I plan on rehoming about 3 of the older girls, I assume my Silkie is a boy so then I would be moving 6 younger ones (at that point they would be 5 months old) in with 6-8 older ones.
